react by changing its state:
CopyC#
CopyC#var mockView = new Mock<IOrdersView>(); var presenter = new OrdersPresenter(mockView.Object); // Check that the presenter has no selection by default Assert.Null(presenter.SelectedOrder); // Raise the event with a specific arguments data mockView.Raise(v => v.SelectionChanged += null, new OrderEventArgs { Order = new Order("moq", 500) }); // Now the presenter reacted to the event, and we have a selected order Assert.NotNull(presenter.SelectedOrder); Assert.Equal("moq", presenter.SelectedOrder.ProductName);
